【转】IOS中截屏的实现，很简易的方法

#import <QuartzCore/QuartzCore.h>

添加QuartzCore.framework库

-(void) screenShot
{
UIGraphicsBeginImageContext(self.bounds.size);
[self.layer renderInContext:UIGraphicsGetCurrentContext()];
UIImage *image= UIGraphicsGetImageFromCurrentImageContext();

UIGraphicsEndImageContext();
NSLog(@"image:%@",image);
UIImageView *imaView = [[UIImageView alloc] initWithImage:image];
imaView.frame = CGRectMake(0, 700, 500, 500);
[self addSubview:imaView];
[imaView release];
UIImageWriteToSavedPhotosAlbum(image, self, nil, nil);
}
